Blackberry (Rubus fructicosus)
Blackberry is a rambling vine with thumb-sized black composite "berries." The plant grows easily in temperate climates, and is often found in recently cleared areas. Laboratory studies have found blackberries to be high in antioxidants, although no benefits were observed in one clinical trial. More research is needed in this area before a potential therapeutic recommendation can be made.
Because of the tannins in the blackberry plant's root bark and leaves, blackberry has been used as an astringent and tonic, and for dysentery (severe diarrhea) and diarrhea. A tea of the root bark has also been used for whooping cough.

Several laboratory studies indicate that blackberry fruit is high in antioxidants, which may be due to the berries' anthocyanin content. However, more research is needed in this area to determine its effects on antioxidant levels in humans.
